Port forwarding to server inside NAT with ip sla applied

Dear all,

I have router with two ISP attached to different interfaces.

In order to provide high availability of the Inernet connection, I configures SLA for both connecitons. In same time, both external interfaces are used for NAT.

Now, I need to perform port forwarding from Internet to some servers inside LAN. Before applying SLA it was quite simple - ip nat inside source static tcp $localIP $localPort $externalIP $externalPort . Unfortunately, it doesn't work when IP SLA is applied.

The question is - how to correctly aply port forwarding with IP SLA configured?

Thank you in advance for any help.

Regards

Piotr

Port forwarding to server inside NAT with ip sla applied

@Cadet

Could you give me an example of command you mentioned? Thank you in advance.

Re: Port forwarding to server inside NAT with ip sla applied

I figured out that port forwarding with approach, which I presented in the first post, works correcly. However, I need to change external IP address.

Unfortunately some ports needs to be availalble only on first public IP. How to achieve such configuration? By adding static routes? This will cause, that IP SLA will be useless imho...

I am confused now...

Thank you in advance for any help.

It looks like this is more complex issue than I thought. I think this issue can be treated as closed - I am moving it to
